Anybody have any experience with h-11 head studs by A1 technologies?
Looking for a more affordable head stud than the arp 625 studs. The h11 seems to be the I between as far as strength and cost goes. I'm going for around 900-1000 hp on my future build. They will be ran with an O-ringed head if at helps. If any one has any experience with these studs please chime in

I've got the regular a1s, they've been installed and torqued to 135 for a few years now and no issues.

They're solid. About the same price as ARP 425's, and are a little higher KSI rating.
You can also fit them with just trimming the ribs on your valve covers instead of machining the pedestals if you don't want to.
They are not as good as ARP 625's though. Or 14mm's.

Are the H11's the same price as the 425's?

Last I checked a couple years ago, they were really close. I could be wrong?

Good luck finding any more a1 h11's. They went out of buisness in the u.s about a year ago. I just tried calling everywhere a few weeks back to see if anyone still had a set. Ended up talking to haisly and went with there stud. They advertise a hmr h11 stud. They actually have arp make 3 different studs to there specs. I think i paid $757 shipped or so for there h11 equivalents which are now actually a L19 material. I was very impressed by them

I was looking for them to post prices comparing and I could not find much, so that's why I didn't. That's good to know.
Do you know the ksi rating for the Haisley HMR H11's?

I got lucky and found a set of H11s new at the end of last year. Got them for a steal too. Ive seen a lot of people happy with the H11s over 425s

Patty Haisley said ARP actually bought the rights to the A1 stud designs and now produce the old A1 style studs. Haisley worked with A1 to develop the design. Whether or not that is still the case I do not know. This was from back in August at Scheid Extravaganza.
When I ordered my most recent set from haisley (standard 12mm) they showed up in an ARP box with haisley instructions in it and a different part number than the standard ARP 425 studs.

Did you have to machine the rockers?

Nope. Showed up in an ARP box and instructions said valve covers may or may not need machining. I might still have the box with the part number on it. It blew my mind when she told me about it. One of the studs ended up breaking on the re-torque and the replacement that ARP sent was from their 425 sets and the stud was completely different in many ways.

My haisley main studs came in arp box with arp stamped in the stud, but the PN brings up as an A1 pn. Reading everything above makes sense.
